Behold the colouring book of swear words, for when pretty patterns won't cut it

If the latest trend of colouring books is a little too prissy for you, we might have found your match.

For all the potty-mouthed souls out there, a British illustrator has created a crass-meets-beautiful colouring book consisting of 20 different swear words, from the generic "F**k" to the more inventive "Twat waffle".

There's also plenty of British curses such as "B**locks" and "Knob".

While artist Sarah Bigwood from Chelmsford, England - who goes by the name PixieRah Design - has already made two colouring books for a small French publisher, she thought one "for the days when only a big swear will do" would be far less mainstream.

She took to kickstarter to raise funds for the book this month and has since received £13,710 in pre-orders. Little did she know the world was full of foul-mouthed people such as herself.

Sales of colouring books skyrocketed this year, as grown-ups turned to the childhood past-time to combat stress and anxiety.

You can download the book for £13 on Etsy right now or order an advanced printed copy for £10.75. Unfortunately, it won't get to you in time for Christmas; Bigwood anticipates a delivery after 10 February.
